Impact of multiple flexible loads on grid stability for Fast Frequency Reserve
(IEEE, 20.11.2024)The increasing share of integrated renewable energy sources results in weaker grids and reduced system inertia, posing challenges to grid stability. To address this, fast frequency reserve (FFR) services are being introduced ... -
Bidirectional electric vehicle smart charging in public charging stations (V2G): use case representation using the e-mobility systems architecture framework
(IET, 01.07.2024)The global shift towards electric vehicles is expected to result in more than 1 billion electric vehicles (EVs) by 2050, providing a substantial source of flexibility for the power system and enhancing the integration of ... -
Investigation of hybrid modeling and its transferability in building load prediction used for district heating systems
(Elsevier, 04.11.2024)In the district heating systems, the historical operation data of the buildings in those areas would be partially or entirely missing. The traditional data-driven model is hard to predict the ground truth results because ... -
Open innovation ecosystems
(Edward Elgar Publishing, 16.10.2023)Defined as a community of hierarchically independent, yet interdependent heterogeneous actors around a focal firm who facilitate innovation through cross-boundary knowledge flows, the open innovation ecosystem extends ... -
Extended multi-stream temporal-attention module for skeleton-based human action recognition (HAR)
(Elsevier, 06.11.2024)Graph convolutional networks (GCNs) are an effective skeleton-based human action recognition (HAR) technique. GCNs enable the specification of CNNs to a non-Euclidean frame that is more flexible. The previous GCN-based ... -
Hydrogen-enhanced entropy (HEENT): A concept for hydrogen embrittlement prediction
(Elsevier, 16.12.2023)The concept of hydrogen-enhanced entropy (HEENT) for hydrogen embrittlement prediction was firstly introduced and discussed through experimental validation methods, multiscale characterization, and trapping studies. The ... -
